Tensions rose in major cities across Nigeria on Monday where tens of thousands of people protested against soaring fuel prices, sparking clashes with police that killed at least one person.

Witnesses say a police officer fatally shot one protester in the main commercial city of Lagos.

Elsewhere in the city, riot police stood watch as protesters blocked roads, burned tires and chanted slogans against the policies of President Goodluck Jonathan.

In the northern city of Kano, the Red Cross says at least 14 people were injured during protests, including seven who suffered gunshot wounds.

Thousands of Nigerians began a nationwide strike on Monday to protest the government's decision to end a popular consumer fuel subsidy last week. Fuel prices doubled in one day to about 88 centers a liter.

The demonstrations have effectively shut down major cities, including the capital Abuja.

The country's major labor unions called for the strikes to pressure the government to restore the subsidy.

National Labor Congress spokesman Owei Lakemfa told VOA the government has rejected the unions' efforts to resume talks on the issue.

An advisor to President Goodluck Jonathan argued the move will benefit citizens in the long run. The government has promised to use the $8 billion saved to invest in the country's infrastructure and social programs.

The fuel subsidy was one of the few benefits Nigerians received from their country's oil wealth. Most people in Nigeria live on less than $2 a day.
